To reduce generation of CO2 when disposing an agricultural sheet after using it by changing the material composition as the agricultural sheet.

The agricultural sheet is obtained by mixing aliphatic polyester of biomass base polymer using fatty acid coming from vegetable systems such as corn starch, sugar cane starch, castor oil, and aromatic aliphatic polyester of at least more than 10 (weight)% of raw material replacing the fatty acid coming from petroleum system raw material. Thereby, carbon neutral of the raw materials coming from vegetables is achieved when disposing it after the use and generation of CO2 is suppressed.
